What is a .AAF file?
Everything worth knowing about Advanced Authoring Format File.
An AAF file is a project interchange file used in professional video and audio post-production. It carries a complete timeline, including edits, transitions, and effects metadata, so it can move between applications such as Avid Media Composer, Avid Pro Tools, Adobe Premiere Pro, and Adobe After Effects. Regular media players cannot open AAF files; you need a compatible NLE or DAW.

Is my .AAF file uploaded to a server?
No. Your .AAF file is converted for you. The converted file is created in memory,.
Why is conversion slower than desktop software?
Browsers give web pages a single CPU core for this kind of work and no hardware video encoder. Short clips convert in seconds; for long 4K films a desktop app like HandBrake is faster. Use Start and Length to convert just the part you need.
Which output format should I pick?
MP4 plays on every phone, TV and browser. WEBM is an open format that's great for the web. MP3 keeps only the sound. MKV (no re-encode) is instant and lossless, but only changes the container.
Can I keep all audio tracks and subtitles?
The MKV (no re-encode) option copies every track as-is. MP4 and WEBM keep the first video and audio track, which is what most players use.
Why can't some files be converted?
Files protected with DRM (for example purchased iTunes .m4p songs or some .wmv rentals) are encrypted. We can show what's inside, but nobody can convert them without the key.
